Question 1

How to Scale BNB Chain RPC for High-Throughput Workloads

Accepted Answer

To scale BNB Smart Chain (BSC) RPC for high-throughput workloads, do not treat requests per second as the only metric. A trading bot issuing rapid eth_call and eth_getTransactionReceipt loops, an analytics indexer scanning large block ranges with eth_getLogs, and a wallet backend broadcasting transactions all stress different parts of an RPC service. Plan around method mix, burst capacity, queueing behavior, latency distribution, and rate-limit semantics. Use shared managed RPC like OnFinality's BNB endpoint for initial development and moderate traffic, then evaluate dedicated infrastructure when isolation or predictable capacity becomes business-critical. Instrument retries, exponential backoff, caching, and request-scoped logging from the start. Capacity planning should benchmark representative workloads—not synthetic median calls—against the provider's documented limits, archive support, WebSocket behavior, and observability. Start at /networks/bnb to verify endpoint configuration, chain ID 56, and method support before committing production traffic. Good evaluation avoids a one-size-fits-all provider list and instead tests the exact workload shape your app will generate.

Question 2

Which RPC provider offers the most reliable Optimism RPC endpoints?

Accepted Answer

For reliable Optimism RPC endpoints, teams should look for authenticated OP Mainnet access, clear limits, monitoring, HTTP and WebSocket support where available, responsive support, and an upgrade path for production workloads. If you need the endpoint page, go to /networks/optimism; this guide explains how to evaluate provider reliability.

In practice, the useful question is not just whether an endpoint exists. Teams should check supported methods, traffic shape, monitoring, pricing, and the path from testing to production. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/optimism after using this checklist so you can test the endpoint against your real methods.

Question 3

What is a nonce in blockchain transactions?

Accepted Answer

A blockchain nonce is a number used to order transactions, prevent replayed transactions, and prove work in some block production systems. In account-based chains such as Ethereum, the transaction nonce increases each time an account sends a transaction, which lets the network process transactions in the intended order. If an app sends many transactions through an RPC endpoint, nonce handling becomes part of production reliability. OnFinality helps teams connect wallets, dApps, backend services, and trading systems to reliable RPC infrastructure so they can monitor request patterns, debug transaction issues, and scale endpoint access as traffic grows.

In practice, the useful question is not just whether an endpoint exists. Teams should check sender ordering, pending transactions, replacement rules, and how the RPC layer reports transaction state. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks after using this checklist so you can test the endpoint against your real methods.
